Transformer Installation, Inspection and Commissioning

I already posted couple of article about power transformer. In this post I will discuss about the indoor transformer installation, inspection and commissioning.

Transformer Indoor Installation:

There is some specification if you want to install a power transformer inside a room. But you can do it when you get the permeation from the government. In my country if we are making a substation and our supply voltage is 11 KV then we can install our transformer inside a room.

But when its 33KV or above then we have to go outdoors. For outdoor substation there is some special specification that you can get form the transformer supplier or the government. But when it’s about the indoor installation then you must need to follow some measurement and those are,

If wall is one side only then transformer body must maintain 0.5m distance from wall.

If wall is two sides then the transformer body must maintain 0.75m distance from each wall.

If wall is three sides the transformer body must maintain 1.0m distance from each wall.

If wall is four sides the transformer body must maintain 1.25m distance from each wall.
